湿法炼锌含铁溶液水热矿化沉铁行为研究OA北大核心CSTPCD
Study on hydrothermal mineralization and iron precipitation behavior in zinc hydrometallurgical process
在常规湿法炼锌过程中,采用黄钾铁矾法、针铁矿法除铁工艺时存在铁渣中铁质量分数低而锌质量分数高、渣量大、无害化处理成本高等难题,为此,本文开展湿法炼锌含铁溶液水热矿化沉铁行为研究.研究结果表明:升高反应温度有利于Fe3+水解生成赤铁矿(Fe2O3),同时促进铁矾物相(MFe3(SO4)2(OH)6)向赤铁矿的转化,铁渣中铁质量分数显著升高;延长反应时间可提高Fe3+沉淀率,并使更多的黄钾铁矾(KFe3(SO4)2(OH)6)转化为赤铁矿;提高氧分压…查看全部>>
In the process of conventional wet zinc smelting,there exist problems in the removal process of iron by jarosite method and goethite method,such as low iron mass fraction and high zinc mass fraction,large slag amount and high cost of harmless treatment.Therefore,the behavior of iron precipitation by hydrothermal mineralization of iron-containing solutions in wet zinc refining was studied in this paper.The results show that increasing the reaction temperature…查看全部>>
